Urban Airship raises $25M to push its messaging message

In-app push messaging specialist Urban Airship bulked up its wallet with $25 million in new funds, raised from August Capital and its previous investors Foundry Group, Intel Capital(s intc), True Ventures and Verizon(s vz)(s vod) (see disclosures). The new round brings Airship’s total funding to $46.6 million.

The extra cash should come in handy if Airship plans to continue its acquisition spree of late. In December the Portland, Ore.,-based startup bought up fellow True Ventures company Tello so it could expand its marketing and branding business into Apple’s(s aapl) Passbook digital wallet. In October, Airship acquired SimpleGeo, adding a location-aware component to its push messaging platform. Though Airship didn’t mention anything about additional acquisitions, it did say it would use the funds to expand internationally.

Disclosure: Urban Airship and Tello are both backed by True Ventures, a venture capital firm that is an investor in the parent company of this blog, Giga Omni Media. Om Malik, the founder of Giga Omni Media, is also a venture partner at True.
